Further a DC Motor is connected to the Relay. In circuit, IR sensor Module output pin is simple connected to the Pin 2 no of Arduino and Relay Module’s input is connected to Pin 7 no of Arduino. Relay is further connected to DC Motor, so DC Motor will be ON whenever IR Sensor Detects any objects in front it.Ĭircuit of this IR Sensor controlled DC Motor with Arduino is simple as shown below: Here IR sensor will detect any object in front of it and Arduino will read the IR Sensor’s output and make the Relay High. Here we will interface IR sensor with Arduino to control DC Motor. Today we are making a simple project with Arduino which uses three basic components that are IR Sensor, Relay Module and DC Motor. We have created many Arduino projects from basic interfacing projects to advanced robotic projects and IoT projects, you can check all of them in our website. So everyone try to use Arduino to make any project, as it is easy and having smooth learning curve. Arduino has become the most popular Microcontroller among students and hobbyists in very less span of time.
